Adapt ScfProgressBar to SfxProgress::SetState taking sal_uInt32

...since 5a6ab81651a98dd726ab7d40101dc81f62895fd4 "tdf#75280 Cleaning up of
sal_uIntPtr usage #2".  mnSysProgressScale had been introduced with
2a7add76241d8a3de05e3d26689a2d16d8b92913 "INTEGRATION: CWS dr20", which mentions
"2004/06/17 14:58:21 dr 1.3.320.2: #i27407# handle limit of SfxProgress
(ULONG_MAX/100)" though the referenced
<https://bz.apache.org/ooo/show_bug.cgi?id=27407> "Save default row format to
decrease Excel file size" does not appear to directly mention any reason for
this particular change.  However, prior to
dbdc29e499abf125b6d6f66de668bc60c88fe599 "INTEGRATION: CWS toolbars2"
SfxProgress::SetState did contain code that multiplied the passed-in value (back
then of type ULONG) by 100, so it appears mnSysProgressScale was meant to
mitigate that.  So even if the original motivation for mnSysProgressScale is
gone, repurpose it to address the mismatch between std::size_t (as meanwhile
used throughout ScfProgressBar) and sal_uInt32 (as meanwhile used throughout
SfxProgress).
